The Oklahoma City Thunder are struggling from three-point range. The main focus has been on Jeremy Lamb but is he the only answer the Thunder have?

Three games into the Oklahoma City Thunder's preseason schedule and the team has yet to turn in a decent 3-point shooting performance.

Yes it is the preseason. But there are still questions surrounding the fact the ball isn't falling through the hoop.

Jeremy Lamb is the main focus after shooting .07 percent (1-13) from three-point range in the first three preseason games. However Lamb is not the only one who hasn't sank anything from beyond the arc.

The team is a combined 22 percent (13-58) from long distance. Reggie Jackson is shooting just under 13 percent (1-8) Thabo Sefolosha is shooting 14 percent (1-7) and Derek Fisher and Andre Roberson are a combined 0-5. If you take away Kevin Durant's 47 percent (8-17) the Thunder are shooting just 12 percent (5-41) from deep.

Obviously 12 percent is not anywhere near what the Thunder are capable of but it is time to start questioning if they will be the three-point shooting team they were a season ago.

Oklahoma City finished third in the NBA in three-point shooting percentage last season at just under 38 percent. Durant Sefolosha and former sixth-man Kevin Martin each shot over 40 percent from three-point land and power forward Serge Ibaka even chipped in at 35 percent.

Losing a player like Martin never helps. The Thunder didn’t re-sign him in the offseason and now he will likely be a starter for the Minnesota Timberwolves.

With Martin out of the picture the Thunder's makeup suggests that unless multiple players not just Lamb step up from long range they will be a middle-of-the-road three-point shooting team.

Even if Lamb starts lighting it up at a 40 percent rate it still won't be enough for the Thunder to develop into a top-5 three-point threat this season. Jackson has to step up and Sefolosha has to find the form he had a year ago. If not the Thunder will be in trouble on multiple situations including the drive-and-dish.
